On December 6, 2025, Sound Transit’s Link extension to Federal Way (FWLE) welcomed its first passengers. This 1 Line extension added three new stations along eight miles of new track south of Angle Lake. The three new stations — Kent Des Moines, Star Lake, and Federal Way Downtown — are located in suburban communities between SR-99 and I-5. Each station has connections to local bus service, pickup and drop-off areas, and lots of parking. In a Board of Directors Meeting on December 18, Sound Transit CEO Dow Constantine shared the three new stations had a combined 16,000 boardings on opening day.

Sound Transit’s ridership dashboard has been updated to include the December ridership data for the three new Link stations. While these initial data can share some insights, it is worth noting a few reasons why this data may not represent future ridership. First, the FWLE opened on December 6, so a week’s worth of ridership is not measured. Second, opening day brought many more riders than usual as people wanted to check out the new stations. Third, King County Metro’s South Link Connections restructure has not been implemented yet. Once these changes are implemented, more south King County residents will have a more direct bus route to a Link station. To reduce the impact of the first two anomalies, the analysis below is focused on the average weekday ridership, adjusted for the number of days the stations were open. With those caveats in mind, let’s take a look at the December ridership data.

This morning, Sound Transit announced the East Link Extension segment between South Bellevue station and International District/Chinatown station will open on March 28, 2026. When it opens, the 2 Line will be extended from South Bellevue station to Lynnwood City Center station, via Seattle. This extension will open two more Link stations: Mercer Island and Judkins Park.

Since the live wire test in September 2025, Sound Transit has run test trains and conducted operator training across the I-90 bridge. In preparation for the extension opening, Sound Transit will begin simulated service for the full 2 Line in February. During this final stage of testing, 2 Line trains will run the full length of the line. Passengers will be allowed on the trains between Downtown Redmond and South Bellevue, and between International District/Chinatown and Lynnwood City Center. Passengers will not be permitted on the trains between International District/Chinatown and South Bellevue.

Today marks the 10th anniversary of the First Hill Line streetcar in Seattle. The 2.5 mile, 10 station line connects Pioneer Square, the International District, Yesler Terrace, First Hill and Capitol Hill. Since 2016, the line has carried over 10 million passengers.

The First Hill Line launched in 2016 after years of delay. Construction of the route was primarily funded by Sound Transit as a mitigation for dropping a proposed First Hill Link station. Sound Transit contributed to funding the route’s operations with $5 million annually until 2023. In 2024 and 2025, the Seattle Transit Measure provided funding to operate both streetcar lines.

Since 2016, most of the discussion around the First Hill Line has focused on the Cultural Connector extension (previously known as the Center City Connector). This extension would connect Seattle’s two streetcar routes via dedicated right of way on 1st Ave. The Cultural Connector was initially scheduled to open in 2020, but has been delayed several times as cost estimates have more than doubled. Let’s take a look at a few key events for the First Hill Streetcar and the Culture Connector from the past 10 years.

Reminder: From 10pm on Friday, Jan. 23, through Saturday, Jan. 24, the DSTT will be closed between Capitol Hill and SODO stations for signal upgrades. Shuttle buses will run every 10-15 minutes. Normal service will resume on Sunday, Jan 25, to serve the NFC Championship game. The Los Angeles Rams will play the Seahawks at Lumen Field at 3:30pm. Edit: the original closure was scheduled for the full weekend, but has been shortened to avoid impacting service for the major sports event.

On New Year’s Eve, SDOT posted a short video highlighting several projects it completed in 2025, distilling a longer summary shared in a blog post earlier in December. The blog post gives roughly equal space to each of its major initiatives, highlighting SDOT’s “Hot Bike Summer” of street improvements, various bridge maintenance projects, ongoing transit improvements, implementation of the Seattle Transportation Plan, community outreach efforts, and traffic incident response.

The 2.5-minute video spends little time showing transit improvement projects, but the opening highlight in SDOT’s video is the Beacon Ave S & 15th Ave S Safety Project. Only a few months after SDOT completed this project, a cyclist named Alley attempted to cross the freshly reworked Beacon Ave S at Stevens Street. Tragically, Alley was struck and killed by a driver who fled the scene.

As ST3 construction cost has skyrocketed, Sound Transit is considering truncating the Ballard line at Smith Cove for now. Ballard riders would need to continue on the bus as very few people live around that station.

When Paris faced similar topography challenges to serve the end of line 8 by bus, they built an aerial gondola line instead. Building such line is far cheaper than extending the subway underground a recent short video explains while still providing faster transit times than the bus lines. The gondola line just opened in December and was built by Doppelmayr who constructed and operates many cable-operated systems here in the U.S. as well as around the world.

That video got a lot of comments saying why public transit can’t work in the US. So Evan made another video refuting these claims. It’s a comedy.

The second video also refers to his walking to school video, which we covered in September

Yesterday, Sound Transit’s Rider Experience and Operations Committee shared an update on the agency’s 2026 Service Plan. Along with aggregated community feedback on the previously shared ST Express service changes, the Sound Transit announced a pilot night-owl route between Sea-Tac Airport and downtown Seattle.

Last year, Sound Transit shared a proposal for three night-owl routes between Seattle and Everett, Lakewood, and Redmond. This proposal was well received with about 90% of survey respondents supporting the proposed routes. Negative feedback on the night-owl routes focused on travel times and the proposed routes not serving all stations.

Before the three night-owl routes are (likely) implemented in Fall 2026, Sound Transit will pilot a night-owl route between downtown Seattle and SeaTac Airport. The new route will provide service between SeaTac/Airport, Tukwila International Blvd, SODO, Stadium, International District / Chinatown, Pioneer Square, Symphony, and Westlake stations. Buses will run every 30 minutes between 12am and 4am.

This route will begin service on March 28 and connect late night/early morning travelers and airport employees with most of King County Metro’s night owl network.

This morning, Seattle Mayor Katie Wilson announced two executive orders delivering on campaign promises: one will accelerate production of emergency shelter and affordable housing, and the other will quickly implement transit improvements starting on Denny Way. Executive Order 2026-01 directs SDOT to “design and install at least one dedicated bus lane on Denny Way, with the goal of significantly improving the reliability, speed, and performance of Route 8 and other transit services operating in the corridor.”

Route 8 has long suffered from chronic congestion on Denny Way in South Lake Union (SLU). The crosstown route uses the only east-west corridor that connects the Seattle Center and SLU with Capitol Hill. Unfortunately, this corridor is also a popular feeder street for I-5. In 2018, an eastbound bus lane was installed on Denny between Minor Ave and Steward St. Despite the one-block-long bus lane, Route 8 continued to flounder in traffic. As South Lake Union has grown, the route’s reliability has continued to suffer. In July 2025, the Fix the L8 campaign hosted a race during which people walked, danced, and paraded on Denny between Dexter and Stewart Avenues faster than a Metro Route 8 bus. Consequently, construction of more dedicated bus lanes on Denny became a significant promise of Wilson’s campaign for Mayor.

Update: The entire T Line will be replaced by buses from Tuesday January 20 at 6:12pm through Friday January 23 evening to replace broken rails. Saturday January 24 may also be affected if necessary. The shuttle buses will have the same schedule as Link and will be free.

Update 2: Metro is looking for part-time drivers. Apply by January 23.

On Monday, Sound Transit announced seats on all Link trains will be upgraded to use vinyl inserts instead of the current cloth covers. This change comes following feedback the agency received during a pilot of these seats in 2024. The vinyl inserts are similar to the vinyl seats that King County Metro first started using in its fleet in 2011.

During the pilot, Sound Transit solicited rider input on the cleanliness, comfort, appearance, and overall satisfaction of the vinyl seats vs the cloth seats. The vinyl seats ranked higher in every category. Additionally, maintenance data showed the vinyl seats are more durable and easier to clean.

When Toronto faced escalating cost on their relief line, instead of extending their existing subway network, they decided to build a separate Ontario line and use lighter and shorter automated trains rather than their prior subway trains. Lighter trains mean faster acceleration, allowing steeper climbs including from within a tunnel to shallow stations and even elevated portions and smaller tunnel diameters. Shorter trains mean smaller stations which can fit more easily into the existing urban landscape. A separate line minimized the impact on the rest of the transit system.

As Sound Transit ponders escalating construction cost, it may want to consider the same. It may not only save them money during construction and operation, it may also provide a better ridership experience.

On Friday, King County Councilmember and Sound Transit Boardmember Claudia Balducci shared a series of updates regarding the cross-lake connection of the Link 2 Line via BlueSky.

In a series of posts, Claudia Balducci shared she previewed the unopened section of the 2 Line with project partners from WSDOT, King County Metro, Sound Transit, and the Federal Transit Administration, saying “the ride was smooth and truly exciting.” The line is performing pre-revenue testing now, but will begin simulating full-time service between Lynnwood and Redmond in February. Answering a question long asked by transit afficionados: Sound Transit is planning to allow passengers to board 2 Line trains operating between Lynnwood and CID during simulated service.

This week Sound Transit announced another batch of work for which it will be “strategically closing” sections of the 1 Line for upgrades and complex maintenance. In summary:

Friday, January 9 to Sunday, January 11 (Now): Buses will replace trains between Capitol Hill and SODO each night from 10pm Friday to noon Saturday and 10pm Saturday to noon Sunday. This closure is for continued installation of advanced signals (ATP) in the former DSTT.

Tuesday, January 13 to Thursday, January 15: Buses will replace trains between Stadium and Mount Baker each night after about 9-10pm, with normal service resuming each morning. This work is part of ST’s monthly maintenance program.

Friday, January 16 to Sunday, January 18: Buses will replace trains between Capitol Hill and SODO each night from 10pm Friday to noon Saturday and 10pm Saturday to noon Sunday for continued ATP installation.

Friday, January 23 to Monday, January 26: Buses will replace trains between Capitol Hill and SODO from 10pm on Friday through the weekend with normal service resuming on Monday morning. This longer closure is for ATP installation and testing.

Check Sound Transit’s service alerts for up-to-the-minute updates. Sports fans will be enthused with a few additional updates ST included in Thursday’s press release:

King County Metro Route 50 travels inbound from Othello station to the Alki beach, via Columbia City, SODO, and Alaska Junction. Outbound trips travel in the reverse direction. In October 2025, Route 50 had 2,803 average weekday boardings.

Average Ridership Per Trip

The plots below show the average weekday ridership by stop in each direction, color-coded by time of day. For a more detailed breakdown of how the plots are set up, please refer to the How to Read the Plots section of the article discussing Route 70.

Route 50 is the primary east-west route in south Seattle. It connects numerous neighborhoods with three Link stations and two RapidRide routes. Route 50 is designed as a coverage route with 20 minute daytime frequencies and numerous detours to better serve specific locations. Some observations:

On January 2, Katie Wilson was sworn in as Mayor of Seattle by the Transit Fairy. Coverage of the ceremony: The Urbanist called her Seattle’s Unabashed Urbanist Mayor. The Stranger thought she came in strong [good]. The Seattle Times ($) quotes Wilson’s slogan “This is your city”. PubliCola celebrates Wilson’s thesis “we need bread, but we need roses too”.
